Welcome to Fabio Le Piane, new Postdoc in our POPULAR research unit on printed organic solar cells! :) Fabio will work on Machine Learning, jointly with Rod MacKenzie @oghmanano.bsky.social

We are offering a postdoc position on simulations/machine learning for printed organic solar cells (+optionally experiments) @deibellab @TUCphys in coop with Rod MacKenzie @oghmanano.bsky.social – Duration about 2 years. Details: mytuc.org/knsv

Jan Anton Koster visited our group in Chemnitz @tucphys.bsky.social, and gave an excellent physics colloquium talk on „Charge transport phenomena in doped organic semiconductors: towards efficient thermoelectrics“. Was great to catch up with you, Jan Anton, and think of nice research ideas with you!

Are you interested in pursuing postdoctoral research on solution-processed semiconductors/optoelectronics via the Marie Skłodowska-Curie or Humboldt Research Fellowship frameworks?

A recent perspective taking a closer look at the transport resistance in OPV and strategies to minimize these charge collection losses in future solar cells has just appeared online: advanced.onlinelibrary.wiley.com/doi/10.1002/...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspe...

This week for the #PhDPostdocSeries we welcome Maria from @deibellab.bsky.social. She will teach us how to decode losses in #OPV! Join us at: syddanskuni.zoom.us/webinar/regi...

Maria's paper "Transport resistance strikes back" is now published: https://doi.org/n687 – very nice, and a professional experience @ioppublishing.bsky.social! To celebrate, I wrote a short blog post on transport resistance, which limits the fill factor in organic solar cells https://wp.me/pbZgX-d0

Congratulations to Maria, who defended her PhD thesis on Fill Factor Losses in Organic Solar Cells today: very well done! Thanks to the committee Martin Breugst @breugstlab.bsky.social, OlavHellwig and Rod MacKenzie! @tucphys.bsky.social

New spectrometer as late Xmas present! Looking forward to use it in our close cooperation with @kretschmerlab.bsky.social and with @skahmn.bsky.social @tucphys.bsky.social !

Two preprints on transport resistance in organic solar cells: joint review with Dieter Neher, Thomas Kirchartz, Uli Würfel & Rod Mackenzie, lead by Maria and Chen. Discussing & writing, really enjoyable! arxiv.org/abs/2412.13694 – And research by Maria, arxiv.org/abs/2404.06190

Our DFG research unit P☀PULAR also celebrates Xmas → Thanks to Jacob Müller for designing the logo, and Martin Dehnert for 3d-printing it! popular-printed-photovoltaics.de @tucphys.bsky.social

Blog post on pitfalls when measuring recombination lifetimes in organic solar cells – this is on the capacitive lifetimes due to (dis)charging carrier concentration across the device capacitance: blog.disorderedmatter.eu/2024/08/22/p... – please have a look if you care:)

Pitfalls when measuring recombination lifetimes in organic solar cells

Six years ago, I came across an interesting publication by David Kiermasch and Kristofer Tvingstedt, [Kiermasch et al 2018], titled Revisiting lifetimes from transient electrical characterization o…
